Six-Card Option poker
A form of six-card stud, found exclusively in home games,
in which each player receives one card face down and one face
up, followed by a round of betting, with a round of betting
after each successive up card, till the fifth card, then a down
card, and then a twist, with a further round of betting; the
game is played high-low. At the showdown, a player uses the
best five of the six cards; (usually) one set of five cards
can be used for high and another for low
